以下僅以實施例說明本發明可能之實施態樣，然並非用以限制本發明所欲保護之範疇，合先敘明。The following merely illustrates the possible implementation forms of the present invention with examples, but it is not intended to limit the scope of the invention to be protected, and will be described first.

請參考圖1至6，其顯示本發明之一較佳實施例，本發明之二段式萬向工具包括一套件1、一驅動件2及一彈性件3。Please refer to FIGS. 1 to 6, which show a preferred embodiment of the present invention. The two-stage universal tool of the present invention includes a kit 1, a driving member 2 and an elastic member 3.

該套件1定義一軸向11，設有一套接部12與一組接部13，該套接部12具有一容置槽14，該容置槽14之內壁設有複數軸向11延伸之卡凸15，其中一該卡凸15設有一凹部16，該組接部13可供與一轉動工具相組接。The kit 1 defines an axial direction 11 and is provided with a set of connecting portions 12 and a set of connecting portions 13. The set of connecting portions 12 has an accommodating groove 14, and the inner wall of the accommodating groove 14 is provided with a plurality of axial directions 11 extending The locking protrusion 15, one of the locking protrusions 15 is provided with a concave portion 16, and the assembly portion 13 can be assembled with a rotating tool.

該驅動件2設有一多角形球頭21，該多角形球頭21設有複數弧面段211，該多角形球頭21係插設於該容置槽14且該等弧面段211係分別抵頂於一該卡凸15，該驅動件2可相對該套件1滑動於一第一位置與一第二位置，該多角形球頭21設有一彈抵件22，該彈抵件22常態地徑向朝外彈抵，於本實施例中該多角形球頭21與該容置槽14皆為六角形，於其它實施例中可為其它角數之多角形。The driving member 2 is provided with a polygonal ball head 21, the polygonal ball head 21 is provided with a plurality of arc-shaped segments 211, the polygonal ball head 21 is inserted into the accommodating groove 14 and the arc-shaped segments 211 are Abutting against one of the locking protrusions 15 respectively, the driving member 2 can slide relative to the kit 1 in a first position and a second position, the polygonal ball head 21 is provided with a resilient resisting member 22, the resilient resisting member 22 is normal The ground deflects radially outwards. In this embodiment, the polygonal ball head 21 and the accommodating groove 14 are both hexagonal. In other embodiments, they can be polygons of other angles.

該彈性件3彈抵設於該容置槽14之底部與該多角形球頭21之間，以使該驅動件2具有朝該第二位置移動之趨勢。The elastic member 3 is resiliently disposed between the bottom of the accommodating groove 14 and the polygonal ball head 21, so that the driving member 2 has a tendency to move toward the second position.

其中，當該驅動件2位於該第一位置時，該彈抵件22係彈抵於該凹部16且該驅動件2係無法以該多角形球頭21為軸而相對該套件1擺動，該驅動件2即與該套件1呈一直線，且該彈抵件22係彈抵於該凹部16，該驅動件2即無法任意移動至該第二位置；當使以一外力將該驅動件2朝該第二位置移動時，該彈抵件22即脫離該凹部16，該驅動件2即被該彈性件3彈抵而移動至該第二位置移動，該驅動件2即以該多角形球頭21為軸而相對該套件1擺動，該套件1與該驅動件2之間即可進行多角度轉動。如欲將該驅動件2再移動至該第一位置時，僅需再施以一外力克服該彈性件3之彈抵力，該驅動件2即可回復至該第一位置，因此該驅動件2可有效快速定位於該第一位置或該第二位置且不會任意相對該套件1滑動，可提高使用上之方便性。於本實施例中該彈性件3係由該組接部13朝該容置槽14之方向漸縮，並抵頂於該多角形球頭21朝向組接部13之端面。Wherein, when the driving member 2 is in the first position, the resilient member 22 resiliently abuts against the recess 16 and the driving member 2 cannot swing relative to the kit 1 with the polygonal ball head 21 as the axis, the The driving member 2 is in line with the kit 1 and the resilient member 22 springs against the recess 16 so that the driving member 2 cannot move to the second position arbitrarily; when the driving member 2 is moved toward the outside with an external force When the second position moves, the resilient member 22 disengages from the concave portion 16, the driving member 2 is resiliently moved by the elastic member 3 to move to the second position, and the driving member 2 uses the polygonal ball head 21 is a shaft that swings relative to the set 1, and the set 1 and the driving member 2 can be rotated at multiple angles. If you want to move the driving member 2 to the first position again, you only need to apply an external force to overcome the elastic resistance of the elastic member 3, the driving member 2 can return to the first position, so the driving member 2. It can be quickly and efficiently positioned at the first position or the second position without sliding relative to the kit 1, which can improve the convenience of use. In this embodiment, the elastic member 3 is tapered from the assembly portion 13 toward the accommodating groove 14, and bears against the end surface of the polygonal ball head 21 facing the assembly portion 13.

該容置槽14另設有複數軸向11延伸之卡凹17，該等卡凸15及該等卡凹17係沿該容置槽14之周向交錯設置，該多角形球頭21之任相鄰該二弧面段211之間形成有一角部212，各該角部212抵頂於一該卡凹17，以防止該多角形球頭21相對該套接部12沿該軸向11轉動。於本實施例中各該卡凸15為弧凸面，各該卡凸15沿該套件1之周向兩側漸薄，以使該多角形球頭21位於該第二位置時，該驅動件2較容易以該多角形球頭21為軸而相對該套件1擺動。The accommodating groove 14 is further provided with a plurality of locking recesses 17 extending in the axial direction 11. The locking protrusions 15 and the locking recesses 17 are staggered along the circumferential direction of the accommodating groove 14. Any one of the polygonal ball heads 21 is adjacent A corner portion 212 is formed between the two arcuate surface sections 211, and each corner portion 212 abuts against the locking recess 17 to prevent the polygonal ball head 21 from rotating relative to the sleeve portion 12 along the axial direction 11. In this embodiment, each of the latching protrusions 15 is an arc convex surface, and each of the latching protrusions 15 tapers along the circumferential side of the kit 1 so that when the polygonal ball head 21 is at the second position, the driving member 2 It is easier to swing relative to the kit 1 with the polygonal ball head 21 as the axis.

該凹部16沿該軸向11之兩側壁161沿該套件1之徑向方向延伸，以避免該彈抵件22任意脫離該凹部16。該凹部16沿該套件1之周向兩側分別設有一漸縮之斜面162，各該斜面162分別延伸至一該卡凹17。另外，該凹部16之軸向11長度與該容置槽14之槽深的比例為1：7至1.5：7，於本實施例中該凹部16之軸向11長度與該容置槽14之槽深的比例為1.3：7，可使該凹部16與該彈抵件22具有較強的卡掣能力。The two side walls 161 of the concave portion 16 along the axial direction 11 extend in the radial direction of the kit 1 to prevent the resilient member 22 from arbitrarily escaping from the concave portion 16. The concave portion 16 is respectively provided with a tapered inclined surface 162 along two sides of the circumferential direction of the kit 1, and each inclined surface 162 extends to a locking concave 17. In addition, the ratio of the axial length 11 of the concave portion 16 to the groove depth of the accommodating groove 14 is 1:7 to 1.5:7. In this embodiment, the axial length 11 of the concave portion 16 and the accommodating groove 14 The ratio of the groove depth is 1.3:7, so that the concave portion 16 and the resilient member 22 have a strong locking ability.

該彈抵件22包括一卡件221及一彈簧222，該多角形球頭21設有一容孔213，該卡件221係滑設於該容孔213且該彈簧222係彈抵於該容孔213之底部與該卡件221之間，使該卡件221限位於該容孔213並常態地朝外抵頂，於本實施例中該卡件221為卡珠，以避免該卡件221與該凹部16卡死而無法脫離該凹部16。The resilient member 22 includes a clamping member 221 and a spring 222, the polygonal ball head 21 is provided with a receiving hole 213, the clamping member 221 is slidably disposed in the receiving hole 213, and the spring 222 is resilient against the receiving hole Between the bottom of 213 and the clamping member 221, the clamping member 221 is limited to the receiving hole 213 and normally abuts outward. In this embodiment, the clamping member 221 is a clamping bead, so as to avoid the clamping member 221 and The concave portion 16 is stuck and cannot be separated from the concave portion 16.

該驅動件2另外一體設有一工作部23及一徑向凸緣24，該徑向凸緣24設於該工作部23與該多角形球頭21之間，該工作部23係供與一鎖固件或一工具套筒相組接，當該驅動件2位於該第一位置時，該徑向凸緣24係與該容置槽14之內壁相抵頂，當該驅動件2位於該第二位置時，該徑向凸緣24即不與該容置槽14之內壁相抵頂。The driving member 2 is additionally provided with a working part 23 and a radial flange 24 between the working part 23 and the polygonal ball head 21. The working part 23 is provided with a lock When the driving element 2 is in the first position, the radial flange 24 abuts against the inner wall of the accommodating groove 14 when the driving element 2 is in the first position, when the driving element 2 is in the second position In the position, the radial flange 24 does not abut against the inner wall of the accommodating groove 14.

較佳地，該容置槽14之內壁遠離該組接部13之一端另設有一環凹槽18，該環凹槽18可拆卸地容設有一擋件19，當該驅動件2移動至該第二位置時，該擋件19係卡抵於該多角形球頭21，以使該多角形球頭21無法脫離該容置槽14，於本實施例中該擋件19為可拆卸於該環凹槽18之C型扣環，以利於拆裝。Preferably, the inner wall of the accommodating groove 14 is further provided with a ring groove 18 at one end away from the connecting portion 13, the ring groove 18 detachably houses a stopper 19, when the driving member 2 moves to In the second position, the stopper 19 snaps against the polygonal ball head 21, so that the polygonal ball head 21 cannot escape from the accommodating groove 14, in this embodiment, the stopper 19 is detachable The C-shaped retaining ring of the ring groove 18 facilitates disassembly and assembly.

綜上，本發明之二段式萬向工具，藉由該彈性件、該凹部及該彈抵件之結構配合，該驅動件可有效快速定位於該第一位置或該第二位置且不會任意相對該套件滑動，可提高使用上之方便性。In summary, the two-stage universal tool of the present invention, through the structural cooperation of the elastic member, the concave portion and the elastic resisting member, the driving member can be effectively and quickly positioned at the first position or the second position without Any sliding relative to the kit can improve the convenience of use.
